Spamming via other hosting facilities which in turn contain links to a domain on our network is also prohibited. We consider spam any mass unsolicited messages or similar activity. You may not use our services or servers for disseminating or hosting harmful content including, without limitation, viruses, Trojan horses, worms, time bombs, cancelbots or any other computer programming routines that may damage, interfere with, surreptitiously intercept or expropriate any system, program, data or personal information.

Items not covered under Web and Social Media Management
IT and technical support. We are unable to advise you on any matter relating to your computer, web browsers, or your specific e-mail setup. We are only able to test and confirm that your server and related email services are running as expected. If we are requested to investigate further then a charge maybe applicable if no fault is found at our end. In addition to this all site visits relating to technical support maybe chargeable. However, if you require IT and technical support, then we do offer this as a separate service.
Guaranteed increased in social media/networking presence. While we will do our utmost to increase your social networking presence, we provide no guarantees relating to targets or specific figures. The service we provide is directly relational to management and therefore is a time-saving and efficiency service.
Design changes outside of the agreed brief and Statement of Work. While minor changes (as detailed above) are perfectly acceptable, larger or total redesigns maybe chargeable and it should not be expected that GlobalSpex, Inc. can make these changes to the design of a site as part of this agreement or package. Major changes are identified as anything outside of the above listed minor changes.
Major development work. This is identified as any work that will require more than 5 hours of research and a further 10 or more hours of development time. If however you wish to undertake this development by reallocating previously agreed services then this can potentially be discussed and worked into an agreement where several months’ worth of development services can be used at once.
Guaranteed returns on investment/income. GlobalSpex, Inc. cannot be held responsible for the targets you set in relation to financial forecasts and the ability for your website to produce this income to be generated by your website. We will endeavor to create a site that, given the correct marketing and product range, will from a technical point of view be capable of creating this income.
At GlobalSpex we want to make the transfer process as seamless as possible. It is in both of our best interests to handle the transfer process expeditiously. Transfers, generally assessed at $90, are provided as a complementary service on shared hosting plans; however it is impossible to estimate the time required to complete a transfer, and we also cannot guarantee the availability of the prior host’s data. For example, we currently cannot offer transfers with ASP websites.
Some hosting providers compile data in incompatible or proprietary formats, making it extremely difficult (sometimes impossible) to migrate portions of your data. Some platforms, like the GlobalSpex Site Manager platform, have differences in core applications that if utilized make transfers unfeasible. Other providers disallow host-to-host transfers all together. If we cannot migrate your data in a timely and efficient manner, we will work with you through this process and notify you beforehand if further services can be offered and provide you with a cost estimate for such additional services.
If we cannot migrate your data in a timely and efficient manner, we will work with you through this process and notify you beforehand if further services can be offered and provide you with a cost estimate for such additional services.
This complimentary service is only available during our 30 day money back guarantee. Transfers outside of the 30 day free period will incur a charge. Please contact support for specific details and to receive a quote if this be the case.

We cannot accept cancellation requests over the phone or be regular email for security and verification reasons.

We charge $15 per year for domain registration. If you cancel your account after the first 30 days have passed, or after your account is renewed then unfortunately we will not be able to issue any refunds.

Terms of Data Transfer (Bandwidth)
If you exceed the data transfer limit of your account you will be notified by GlobalSpex to resolve the situation and be given options for upgrading your account. E-mail warning notices will be sent upon approaching your limit. Once the limit is hit, data transfer will be stopped.
The use of your account must be reasonable and you may not place excessive burdens on our servers. While our shared services are suitable for the bulk of our customers, there comes a time that your website(s) are better suited for a larger hosting package, which allows for more dedicated CPU and memory resources. We reserve the right, in our sole discretion, to discontinue service to any customer with a website or other hosted data that uses a high amount of server resources (such as, but not limited to, CPU Time, Memory Usage, and Network Resources). At our election, you will be given an option of either upgrading the service level or reducing the resource usage to an acceptable level, otherwise we reserve the right to limit your use of our servers or take your site offline. Due to the severity of this, and our ability to act quickly to correct these situations to avoid server issues, we will do everything reasonably feasible to provide you with a warning prior to taking your site offline, but we accept no obligation to do so.
